Just for the clarity, the first quest you start searches for a questgiver in a set radius around you, but when another npc gives you a quest, he searches for another npc in a radius around him, so it can get relatively farther and farther away from your base. The distance between questgivers doesn't change, it's just that questgivers make a "chain" that goes further and further as you complete quests.
